https://www.rd.go.th/english/37749.html#section48 Section 48 (3) (3) The taxpayer may elect to pay tax at the rate of 15.0 per cent of the following income under Section 40 (4) (a) and (g) instead of calculating the amount of tax as under (1) and (2): ... My understanding is that you have the choice to select the 15% WHT on interest as a final tax thus not to be declared. More information: https://sherrings.com/interest-income-personal-tax-thailand.html

That is unclear and anyway unenforceable since non residents do not have to file for foreign sourced income remittances.

It's 15% tax on interest. PWC: "Interest received from bank deposits, loans to finance companies, debentures, and bills issued by a corporate entity is subject to WHT at a flat rate of 15%. Individuals may choose to exclude interest income from other income, in which case they pay the 15% WHT, or they may choose to include such interest income with other income and pay tax according to the PIT rates, in which case the tax withheld at source is credited against the tax liability."

Indeed, FATCA W-9 form is used for US persons. However, if you have additional tax residence in countries other than the US, Thai FIs should require you to fill a CRS form as well. Example: MFC Asset Management FATCA/CRS Self-Certification Form https://did-admin.mfcfund.com/Uploads//Website/Registrar/Forms_TH/d7d311c62a52.pdf

CRS rules apply to FIs, FIs should apply CRS requirements to all their customers regardless of their citizenship. That's the case worldwide. Now, who knows how Thailand will operate.

Foreign and Thai customers as well. Or are you implying that Thai banks will discriminatorily assume that Thai people can't hold other tax residences nor bank accounts outside of Thailand (thus their Thai bank accounts don't need to be reported to other countries)?

So what do you suggest? Moving address to another TRD jurisdiction that will accept you to file in order to pay tax? Sue the ignorant local TRD office because they don't allow you to file?... Any other smart-ass idea?

Indirect taxation is the efficient way to proceed. To me, putting the onus on the individual to declare and pay taxes with very random checks is nonsensical and counterproductive as the figures show.

We can imagine the impressive watches collection held by some high ranking TRD officials.

IMO less risky than having a visa/extension illegally stamped in your passport.

How so? Is the decision on visas / extensions in your hands? No. All your life decisions, including deciding you're going to pay tax or not, are in your hands unless you are a muppet. Needless to say, all the consequences of your decisions shall be assumed.

Muppet comment.

Who's gonna check how Thailand, within its borders, complies and the data accuracy/exhaustivity they'll provide?

This quote does not apply to Thailand.

Inheritances and gifts are tax exempted and not to be filed if under threshold.

Trolling accounts have an expiry date.

One reason why the unemployment rate in Thailand is impressively low.

I rectified to better fit the reality.

In order to keep pretending public servants being busy and continue milking increasing tax money, bureaucracy can be quite creative.

You're addressing to a ghost.

TRD auditors can ask for information going back 10 years, past this period everything becomes savings.

Because, unlike some people may think, history keeps repeating itself in Thailand.

Green Card holders are required to obey all U.S. laws and file taxes annually, just like citizens. However, they face limitations, such as not being allowed to vote in federal elections or hold certain government jobs. Extended absences from the U.S. may also jeopardize their LPR status. I will not argue further over few limitations for some few countries, that's pointless. My question, which is more important, remains: "But what's your point? Because some countries discriminate its residents then it's OK?"
